Trisomy for the Proximal Segment of the Long Arm of Chromosome 13A New Entity?

Am J Dis Child. 1974;128(2):221-222. doi:10.1001/archpedi.1974.02110270095020

A case of trisomy for the proximal portion of the long arm of chromosome 13 is described in a child who has a few congenital defects. This anomaly has been traced to a balanced 6/13 chromosomal translocation in the mother. A review of six cases, also trisomic for the proximal portion of the long arm, makes it possible to delineate a new clinical entity in which a small number of the clinical findings, commonly observed in the full trisomy 13, are present.
